Given:

The base of an isosceles triangle is 16 cm long.

The equal sides are each 22 cm long.

To find:

The height of the triangle.

Solution:

We know that the altitude of an isosceles triangle divides the base into two equal parts as shown in the below figure.

According to the Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Using Pythagoras theorem, we get

[tex]22^2=h^2+8^2[/tex]

[tex]484=h^2+64[/tex]

[tex]484-64=h^2[/tex]

[tex]420=h^2[/tex]

Taking square root on both sides, we get

[tex]\sqrt{420}=h[/tex]                  (Because side cannot be negative)

[tex]2\sqrt{105}=h[/tex]

Therefore, the height of the isosceles triangle is [tex]2\sqrt{105}[/tex] cm. Approximate height is 20.49 cm.

Answer:3

Step-by-step explanation:

Answer:

m = 3

Step-by-step explanation:

Notice how x increases by 6 from 3 to 9.  6 is the 'rise.'

Simultaneously, y increases by 2 from -9 to -7.  2 is the 'run.'

The slope, m, is defined as m = rise / run.

Here, m = 6/2, or m = 3

Answer:

Jailyn and her 3 friends will each receive 1/8 of the original pizza.

Step-by-step explanation:

Given that Jailyn has ½ of a pizza left over and she is sharing that with 3 friends, it means that the left over will be divided in 4 pieces and you have to divide 1/2 by 4 to find the fraction of the original pizza that Jailyn and her 3 friends will each receive:

[tex]\frac{1}{2}[/tex]÷4= [tex]\frac{1}{2}[/tex]÷[tex]\frac{4}{1}[/tex] = [tex]\frac{1*1}{2*4}[/tex] = [tex]\frac{1}{8}[/tex]

According to this, the answer is that Jailyn and her 3 friends will each receive 1/8 of the original pizza.

Answer:

$10,857.8

Step-by-step explanation:

Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?

A = p(1 + r/n)^nt

P = A / (1 + r/n)^nt

P = 17000 / (1 + 0.09/12)^(12*5)

= 17,0000 / (1 + 0.0075)^60

= 17,000 / (1.0075)^60

= 17,000 / 1.5657

= 10,857.8

P = $10,857.8

Answer:

D. The probability of selecting an orange is ³/₅.

Step-by-step explanation:

A is incorrect because there would be 4 apples combined (3 from bag one, 1 from bag two). That makes the chance of selecting an apple 2/5 (40%), not 3/10 (30%).

B & C are incorrect because 4/10 (40%) is less than 6/10 (60%)

That leaves D, which state that you have a 60% (3/5) chance selecting an orange, as our answer. That is correct as 3/5 = 6/10 = 60%.

Given:

The given limit problem is:

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]

To find:

The value of the given limit problem.

Solution:

We have,

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]

In can be written as:

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{x^2}{x^4}+\dfrac{3}{x^4}[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{1}{x^2}+\dfrac{3}{x^4}[/tex]

After applying limits, we get

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\dfrac{1}{0^2}+\dfrac{3}{0^4}[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty+\infty[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty[/tex]

Therefore, the value of the given limit problem is [tex]\infty[/tex].

Answer:

26

Step-by-step explanation:

Use the Pythagorean Theorem.

c^2 = a^2 + b^2

a = 10

b = 24

c = ?

c^2 = 10^2 + 24^2

c^2 = 100 + 576

c^2 = 676

sqrt(c^2) = sqrt(676)

c = 26

Answer:

Stephen gets £147

Step-by-step explanation:

Given

Let

[tex]S = Stephen; B = Bridget; R = Richard[/tex]

So:

[tex]S + B + R = 490[/tex]

[tex]R = 2S[/tex]

[tex]S = 3B[/tex]

Required

Find S

Make B the subject in [tex]S = 3B[/tex]

[tex]B = \frac{S}{3}[/tex]

Substitute: [tex]R = 2S[/tex] and [tex]B = \frac{S}{3}[/tex] in [tex]S + B + R = 490[/tex]

[tex]S + \frac{S}{3} + 2S = 490[/tex]

Take LCM

[tex]\frac{3S + S + 6S}{3}= 490[/tex]

[tex]\frac{10S}{3}= 490[/tex]

Solve for S

[tex]S = \frac{490 * 3}{10}[/tex]

[tex]S = 49 * 3[/tex]

[tex]S = 147[/tex]

Stephen gets £147

Answer:

lower bound: 2.996

upper bound: 3.244

Step-by-step explanation:

The value that Helen wants to use is Pi = C/D. The lower bound value is 3.065, and the upper bound for Helen's value is 3.165.

The circumference is the perimeter of the circle.

Given, the circumference, C, at 405 mm to three significant numbers.

She correctly estimates the diameter, d, to be 130 mm to two significant numbers.

Helen wants to find the value of Pi using the formula pi=C/D

We have, the circumference of the circle = C = 405 mm

The diameter of the circle = d = 130 mm

Pi = C/D

= 405 mm / 130 mm

= 405 / 130

= 3.115

3.115, measured to the nearest 0.1.

The degree of accuracy is nearest 0.1.

0.1/2 = 0.05

Upper bound = 3.115 + 0.05 = 3.165

Lower bound = 3.115 - 0.05 = 3.065

Therefore, the lower bound and upper bound for Helen's value are 3.165, and 3.065.

Answer:

the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

Step-by-step explanation:

The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:

Let us assume the package of chocolate chip cookie be x

And, the package of ginger bread is y

So,

According to the question

6x + 2y = $72

6x + 10y = $216

Now subtract equation 1 from equation 2

-8y = -144

y = $18

And, for x it would be

6x + $36 = $72

x = $6

Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

Step-by-step explanation:

First note that the rule for a rotation by 270° about the origin is (x,y)→(y,−x)

Note that the coordinates were swapped and the x coordinates negated. Similarly;

Given the coordinate of the point U as (a, b), if the triangle is rotated 270degrees clockwise, the resulting coordinate will  be (b, -a)
